An array came as a PHP variable. It can store multiple values in a single array. It can be one dimensional or multidimensional too. You can use numeric value or and string as an index of the array.

Simple Array Example:

<?php

$array = array(

    “fname” => “First name”,

    “lname” => “Last name”,

);

?>

There are following types of Arrays:

• Indexed arrays – An array with numeric index or keys
• Associative arrays – An array with named or string index or keys
• Multidimensional arrays – An array contains one or more arrays.

Indexed arrays:

Here is an example of indexed array:

$name= array(‘A’,’B’,’C’);

Or

You can write it like:

$name[0]=’A’;

$name[1]=’B’;

$name[2]=’C’;

If you want to use any specific indexed value in your program then you can use the below example too:

Q: Create an array of names and print second name of array.

A:  To do this you need to write the following:

<?php

//Creating an array

$name=array(‘Tim’,’Peter’,’John’,’Anna’);

echo $name[1];

//Here we used index 1 as array index starts from 0. This will return an output Peter.

?>

Associative arrays : Associative array is an array which used named key as index like

$student_name=array(‘fname’=>’Aarav’,’lname’=>’Maurya’);

Or you can assign values as follows:

$student_name[‘fname’]=’Aarav ’;

$student_name[’lname’]=’Maurya ’;

Multidimensional arrays: An array with one or more array called Multidimensional arrays. You can manage multiple level arrays in php but mostly more than 3 level will be hard to manage or keep remembering for programming.

Here is an example of students of class:

$students=array(

array(‘fname’=>‘Tom,’lname’=>Holland,’e_no’=>1,’marks’=>85),

array(‘fname’=>‘Aarav ’,’lname’=>’Maurya ’,’e_no’=>2,’marks’=>80),

);
